RICHARDS, OF SAME PLACE.

I IMPROVEMENT IN LUBRIGATING COMPOUNDS.

Specification forming part of Letters Patent No. 115,342, dated May 30,1871.

I, ADOLPH MILLOCHAU, of the city and 7 State of New York," have inventedanew and useful Improvement in the Manufacture of Lubricating Compoundsfor Lubricating Mat chinery and for other purposes; and hereby declarethe following is an exact description thereof.

The compound is produced in three forms: first, a semi-fluid substancefor use in any of the lubricating-cups; second, an oil or liquid 7substance, to be used with-or without cottonwaste or any proper packing;and third, combining, withthe semi-fluid substance or compound, animalhair;

1 take ten pounds of caustic soda, in liquid form, at about 16 Baumscale, twenty pounds of a good qualty of tallow, and forty pounds ofscale, and the wholeforms a uniform semifiuid substance when cold. Inthis operation the compound will lose about twenty-three per cent. ofits weight, and will be prevented from melting ortaking fire fromordinary or light friction, and beleft of a consistency and tenacityofordinary lubricating grease.

This mixture, in ,the condition left by the foregoing treatment, isplaced in bags or othor similar inclosures, and submitted to pressure toany desirableextent, and should be so pressed until as much of the oilor liquid substance as desirable is removed.

The liquid or oil thus removed forms a superior lubricator, to be usedwith or without cotton-waste or other suitable packing, as other oils orother liquids are or may be used for lubricating purposes; and thesemi-fluid compound left in the press may be applied by means oflubricating-cups or other similar ap' pliances and in any desirablemanner.

To the pressed or semi-fluid product of the compound I add animal hairin about the proportion of five pounds of hair to one hundred pounds ofthe pressed product, and thoroughly mixand incorporate them. Inthis-form it may be used in the ordinary lubricating boxes orreceptacles without cotton-waste or other packing.

While I believe that the combination of materials and treatmentdescribed will produce the best results, I do not desire to beunderstood as limiting .my invention to the exact proportions named orthe precise treatment described; but

What I claim, and desire to secure by Let- Dated April 29, 1871. A.MILLOGHAU.
